Application filed December 22, 1914. Serial No. 878,559.

To all whom it may concern Be' it known that I, JOSEPH citizen of theUnited States, of Louisville, in the county of Jefferson and State ofKentucky, have invented certain new and useful Improvements in Sewing-Machines; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use thesame. Thisinvention relates to improvements. in sewing machines", and moreparticularly to an auxiliary therefor to facilitate the sewing of loopsto straps, such for'example, as harness straps,-one object of theinvention H. SCHAAF, a

' being to provide a simple device which will enable a loop to bestitchedto' the top of a strap sothat the stitching may be readilyextended through those portions of the loop which overlie the strap andunderlie the vfoot Which.shall be especially body of the loop at bothends of the latter.

A further ob ect is to provide a presser crowd the overlying portion ofa loop back sufficiently to permit the loop to be stitched onto a strapat both ends of the loop. j

With these and other objects in view, the invention consists in certain.novel features of construction as hereinafter set forth and pointed outin the claims.

In the accompanying drawings, Figure 1 is a view in side elevation ofapresser foot "embodying my improvements, Fig. 2 is a sectional viewonthe line 22 of Fig. 1, and Fig. 3 is a sectional view on the line 3-3 ofFig. 1

1 represents the. upright body portion of the device provided at its.upperend with a perforated head 2 which will facilitate its attachmentto the presser footholder of a sewing machine. At the lower. end, thebody portion 1 is provided with a horizontal member 3 having a slot 4for the accommodation of the needle" andawl of the sewing machine, andsaid member may also be provided with projections 5 on its bottom faceto come in direct contact with the work.

At its forward end, the member 3 is provided with a finger 6 whichprojects upwardly and slightly forwardly,said finger position. and aresident adapted to being thus disposed in a forwardly inclined Thefinger 6 is slightly curved or beveled transversely toward one of itsedges, and has a general tapering form from its base to its free upperend. At the base of the finger 6, a forwardly projecting toe 7 isprovided toenter the loop on the strap and force the same upwardly.

In using my improvements, the loop on the strap will be pressed againstthe finger 6. If the loop fits closely upon the strap, the toe 7 willfirst enter under thelsame and force it' upwardly, so that pressure ofthe edge of the loop against the beveledffinger which normally overliethe fastened portions of said loop.

If desired, my improved presser foot may be used in conjunction with andat one side of the ordinary presser foot or it may be permanentlysecured to the latter.

Having fully described my invention what I claim as new and desire tosecure by Lettors-Patent, is

1. Asewing' machine attachment for facilitating the stitching of a loopto a strap, comprising a presser foot having a needle slot in itshorizontal portion and provided at the forward end of said horizontalportion with an upwardly and forwardly p'roje'ctingfinger having itsloop engaging forward face beveled transversely from one side to theother.

. 2. A sewing machine attachment for fa: cilitating the stitching of aloop to a strap, comprising a slotted presser foot provided at itsforward end with an upwardly and forwardly projecting tapering fingerhaving its forward face beveled transversely from one side to the other,and a short toe at the base of said finger In testimony whereof, I havesigned this specification in the presence of two subscrily ingwitnesses.
